Money, that unreliable buyer of happiness, has at times proven effective at delivering good sound. It can buy other things, as well: Audiophiles can swap cash for products that function as objets d'art, as status symbols, or even as canny investments.

But—do you think money can buy peace of mind for the audio enthusiast who frets over binding voice-coils, leaking capacitors, drifting resistor values, oxidizing connectors, aging or incorrectly biased tubes, and that most pernicious worry of all, distortion and premature record wear from incorrectly aligned phono cartridges? Sadly, most of those neuroses, some quite reasonable, remain unaddressed by cash almighty.

Early in 2019, three jazz CDs appeared on a new record label. They were Jason Palmer's Rhyme and Reason, Johnathan Blake's Trion (both double CDs), and Eric Alexander's Leap of Faith. The label was Giant Step Arts.

Given that hundreds of jazz records—many of them good— are released every month, and that new jazz labels pop up all the time, is the release of three new albums really news?

Apple may not have been the first to market with a portable digital audio player, but its original iPod defined the genre: a device small enough to fit into a shirt pocket. When companies like Acoustic Research, Astell&Kern, Fiio, HiFiMan, and Questyle introduced portable players that could play high-resolution files, they echoed the iPod's form factor. The exception was the Toblerone-shaped PonoPlayer, but even that was small. The subject of this review is another exception: The DMP-Z1, from Sony's Signature Series, is comparatively enormous—almost the size and weight of a regular preamplifier. At $8500, it's also considerably more expensive than other players.
